Neilsen - Call of Duty buzz up 400% since Black Ops 2 reveal

Nielsen Media has told GI International the NM Incite tracking buzz around the Call of Duty since the Black Ops 2 reveal has increased 400% due to its mention on social media sites and over 160 million blogs and message boards.

As of April 30, there were 4,911 messages on various boards regarding the game, and after the trailer aired and more details were revealed on May 2, the number of messages reached 21,454.

"Historically, buzz has been at its highest around launch time for Call of Duty, generating up to 69,942 messages on a single day," NM Incite analyst Mickey Campione said. "As far as pre-launch buzz goes, today's buzz total of 21,454 is second highest, only to May 31, 2011's 21,728 messages. The buzz on [that day] came after Activision announced their Call of Duty: Elite online community.

Xbox 360 was the platform leading the discussions, unsurprisingly, but PS3 wasn't far behind which suggests the console's mindshare is growing, according to Nielsen.

Black Ops 2 is out in November.
